Description

Verpackte Beatmunαsmaske Packed Beatmunαsmaske
Die Erfindung betrifft eine verpackte Beatmungsmaske nach dem Oberbegriff des Patentanspruchs 1, die es dem Anwender ermöglicht, einen Patienten ohne Kontakt zu Haut, Schleim¬ haut oder Körpersekreten Mund-zu-Mund, Mund-zu-Nase oder mit einem Beatmungsbeutel zu beatmen. Eine derartige Beatmungs¬ maske ist aus der US 5 121 745 bekannt. Diese bekannte Maske ist selbstaufblasend und weist einen mit Luft befüllbaren Wulst auf.The invention relates to a packaged respiratory mask according to the preamble of claim 1, which enables the user to ventilate a patient mouth-to-mouth, mouth-to-nose or with a resuscitation bag without contact with skin, mucous membrane or body secretions. Such a breathing mask is known from US Pat. No. 5,121,745. This known mask is self-inflating and has a bead that can be filled with air.
Grundsätzlich sind Beatmungsmasken in verschiedensten Be¬ reichen der Medizin, insbesondere in der Anästhesie und Notfallmedizin bekannt. Diese Masken decken normalerweise Mund und Nasenbereich ab und bestehen aus elastischem Mate¬ rial. Die Masken werden von Hand leicht angepreßt oder von Bändern gehalten. Derartige Masken sind aus der GB-PS 841 104, DE 42 12 259 Cl, DE 43 12 215 Cl oder aus der US 3 538 913 bekannt.Ventilation masks are known in a wide variety of areas of medicine, in particular in anesthesia and emergency medicine. These masks normally cover the mouth and nose area and consist of elastic material. The masks are lightly pressed on by hand or held by ribbons. Such masks are known from GB-PS 841 104, DE 42 12 259 Cl, DE 43 12 215 Cl or from US 3 538 913.
In Wiederbelebungssituationen wird vom Ersthelfer, wenn keine entsprechenden medizinischen Gerätschaften vor Ort sind, zur Aufrechterhaltung der Oxygenierung die Mund-zu¬ Mund oder Mund-zu-Nase-Beatmung gefördert. Dabei kann es durch den Körperkontakt zur Übertragung von Infektions¬ krankheiten kommen. Vom Fachpersonal wird die Beatmung bis zum Einführen eines Beatmungsschlauches in die Luftröhre mittels einer Mund und Nase umschließenden, glockenförmigen und nach außen durch einen Wulst abgedichteten Maske und einem daran angeschlossenen komprimierbaren Ballon mit SauerstoffZuleitung durchgeführt.In resuscitation situations, the first-aider, if no corresponding medical equipment is on site, promotes mouth-to-mouth or mouth-to-nose ventilation to maintain oxygenation. In this case, physical contact can lead to the transmission of infectious diseases. Ventilation is carried out by specialist personnel until a ventilation tube is inserted into the trachea by means of a bell-shaped mask enclosing the mouth and nose and sealed off from the outside by a bead and a compressible balloon connected thereto with an oxygen supply.
Für den Ersthelfer werden zum Schutz vor Kontamination bislang verschiedene Hilfen angeboten. Diese zeichnen sich entweder durch zu sperriges Packvolumen oder durch unzurei¬ chenden Schutz vor Kontamination (Bedecken von Mund und Nase durch eine Folie) aus. Einige müssen mit einem Mundstück tief in den Mund des Patienten eingeführt werden (DE-GM 87 09 867) .So far, various aids have been offered to first-aiders to protect against contamination. These are characterized either by too bulky packing volume or by insufficient protection against contamination (covering the mouth and nose with a film). Some have to be inserted deep into the patient's mouth with a mouthpiece (DE-GM 87 09 867).
Aus der DE-OS 22 44 887 ist eine Atemmaske aus Integral¬ schaum bekannt, in deren Innerem eine Plexiglasversteifung verläuft.A breathing mask made of integral foam is known from DE-OS 22 44 887, inside which a plexiglass stiffener runs.
Es ist das der Erfindung zugrundeliegende Problem (Aufgabe) , eine Beatmungsmaske der eingangs genannten Art dahingehend weiterzubilden, daß diese einfacher hergestellt werden kann und in komprimiertem Zustand ein kleineres Packungsvolumen einnimmt.It is the problem (object) on which the invention is based to further develop a respiratory mask of the type mentioned at the outset in such a way that it can be manufactured more easily and takes up a smaller pack volume in the compressed state.
Die Lösung dieser Aufgabe erfolgt durch die Merkmale des Patentanspruchs 1.This object is achieved by the features of patent claim 1.
Durch die erfindungsgemäße Lösung ist eine Maske geschaffen, die im ungebrauchten Zustand sehr klein verpackt ist (Schlüs¬ selanhängerprinzip) und gleichzeitig leicht und schnell zu handhaben ist. Die Maske beherbergt keine Verletzungsgefahr für den Patienten und gleicht im gebrauchsfertigen Zustand einer normalen Beatmungsmaske. Somit kann sie zum einen nach vom Ersthelfer begonnener Wiederbelebung vom Fachpersonal bis zur Einführung eines Beatmungsschlauches weiterverwendet werden. Andererseits kann die erfindungsgemäße Maske in Notfallausrüstungen, die klein verpackt sein müssen (Berg¬ wacht, Hubschrauber, Expeditionen, ...), die bislang bekann¬ ten und relativ sperrigen Masken ersetzen.The solution according to the invention creates a mask which is packaged very small when not in use (key fob principle) and at the same time is easy and quick to use. The mask does not pose any risk of injury to the patient and, when ready for use, resembles a normal ventilation mask. Thus, on the one hand, after resuscitation started by the first aider, it can be used by the specialist staff until the introduction of a ventilation hose. On the other hand, the mask according to the invention in Emergency equipment that has to be packed in small packages (mountain rescue service, helicopter, expedition, ...) that replace previously known and relatively bulky masks.
Vorteilhafte Ausführungsformen der Erfindung sind in den Unteransprüchen beschrieben.Advantageous embodiments of the invention are described in the subclaims.
Das Gehäuse kann in den Ausmaßen etwa einer Filmpatrone entsprechen. Der Schaumstoffkörper kann mittels Vakuum komprimiert sein und in Folie eingeschweißt sein. Durch Brechen des Vakuums läßt sich die Maske in Sekundenschnelle in die Gebrauchsform bringen. Denkbar ist auch ein Entstehen und Aushärten der Maskenform durch Aufschäumen zweier flüs¬ siger Schaumstoffkomponenten in der vorgeformten Folie.The dimensions of the housing can correspond to that of a film cartridge. The foam body can be compressed by means of vacuum and can be welded into film. By breaking the vacuum, the mask can be brought into the shape of use in a matter of seconds. It is also conceivable for the mask shape to form and harden by foaming two liquid foam components in the preformed film.
Wesentlich für die erfindungsgemäße Vorrichtung ist somit, daß anstelle der bisher verwendeten sperrigen Masken oder kleinen Masken ohne ausreichenden Schutz nunmehr mit einem komprimierbaren Schaumstoffkörper gearbeitet wird, der in gebrauchsfertigem Zustand den im klinischen Alltag zur Narkoseeinleitung verwendeten Beatmungsmasken stark ähnelt. Dadurch wird die Akzeptanz beim Fachpersonal erhöht. Durch das kleine Packvolumen wird ein ständiges Mitführen geför¬ dert (Schlüsselanhängerprinzip) , was insofern vorteilhaft ist, als Wiederbelebungssituationen immer und überall auftreten können. Das Unterbringen einer Beatmungsmaske im Verbandskasten eines Autos ist allgemein unzureichend.It is therefore essential for the device according to the invention that instead of the bulky masks or small masks used hitherto without adequate protection, a compressible foam body is now used which, when ready for use, is very similar to the respiratory masks used in everyday clinical practice to induce anesthesia. This increases acceptance among specialist staff. Due to the small packing volume, constant carrying is promoted (key fob principle), which is advantageous in that resuscitation situations can occur anytime and anywhere. Placing a respiratory mask in the first aid kit of a car is generally insufficient.
Das Gehäuse kann Sollbruchnähte aufweisen. Ferner kann ein Filter oder ein Rückschlagventil im Dombereich der Maske vorgesehen sein, wodurch auch bei Mund-zu-Maskenbeatmung zusätzlicher Schutz vor Kontamination entsteht.The housing can have predetermined breaking seams. Furthermore, a filter or a check valve can be provided in the dome area of the mask, which provides additional protection against contamination even in the case of mouth-to-mask ventilation.
Bei der erfindungsgemäßen Maske handelt es sich um einen Einmalartikel. Der Schaumstoffkörper kann jedoch als Recyclingmaßnahme nach Trennung einer ihn umhüllenden Folie und nach entsprechender Reinigung erneut in eine neue Folie eingebracht werden.The mask according to the invention is a disposable item. The foam body can, however, as Recycling measure after separation of a film enveloping it and after appropriate cleaning be reintroduced into a new film.
Ein Ausführungsbeispiel der Erfindung wird unter Bezugnahme auf die beigefügten Zeichnungen rein beispielhaft erläutert. Es zeigen:An embodiment of the invention is explained purely by way of example with reference to the accompanying drawings. Show it:
Fig. 1 eine perspektivische Ansicht einer verpack¬ ten Beatmungsmaske gemäß der Erfindung; und1 shows a perspective view of a packaged ventilation mask according to the invention; and
Fig. 2 eine perspektivische Ansicht einer erfin¬ dungsgemäßen Beatmungsmaske in ihrem Gebrauchszustand.2 shows a perspective view of a respiratory mask according to the invention in its state of use.
Fig. 1 zeigt ein Gehäuse 1, in dem sich die komprimierte Beatmungsmaske befindet, das in der Praxis beispielsweise eine Grundfläche von 4 cm Durchmesser und eine Höhe von etwa 5 cm aufweist. In diesem Gehäuse, das aus Kunststoffolie besteht, ist der komprimierte Schaumstoffkörper 2 (vgl. Fig. 2) eingeschweißt. Das Gehäuse 1 läßt sich öffnen, indem die Sollbruchnähte 3 geöffnet werden.1 shows a housing 1 in which the compressed respiratory mask is located, which in practice has, for example, a base area of 4 cm in diameter and a height of approximately 5 cm. The compressed foam body 2 (see FIG. 2) is welded into this housing, which consists of plastic film. The housing 1 can be opened by opening the predetermined breaking seams 3.
Wie aus Fig. 1 zu erkennen ist, verlaufen die Sollbruchnähte 3, welche in die Folie eingearbeitet sind, parallel neben¬ einander und an der zylindrischen Mantelfläche des Gehäuses 1. In der Mitte des Gehäuses 1 ist eine weitere Sollbruch¬ naht vorgesehen, die als Umfangsnaht ausgebildet ist. Auf diese Weise läßt sich das Gehäuse sehr leicht öffnen, indem die beiden Gehäusehälften, die zu beiden Seiten der Umfangs¬ naht liegen, mit jeweils einer Hand gegriffen und gegenein¬ ander verdreht werden. Hierdurch platzen die Sollbruchnähte 3 des Gehäuses 1 schlagartig auf, so daß sich der Schaum¬ stoffkörper 2 der Beatmungsmaske expandieren kann. Solange sich die Beatmungsmaske in ihrem komprimierten Zustand in dem Gehäuse befindet, läßt sich diese leicht transportieren. Zu diesem Zweck kann auch ein Anhänger oder Schlüsselanhänger (Fig. 1) vorgesehen sein, der an dem Gehäuse befestigt ist.As can be seen from FIG. 1, the predetermined breaking seams 3, which are incorporated into the film, run parallel next to one another and on the cylindrical outer surface of the housing 1. In the center of the housing 1, a further predetermined breaking seam is provided, which is designed as Circumferential seam is formed. In this way, the housing can be opened very easily by gripping the two housing halves, which lie on both sides of the peripheral seam, with one hand and rotating them against one another. As a result, the predetermined breaking seams 3 of the housing 1 burst open suddenly, so that the foam body 2 of the respiratory mask can expand. As long as the ventilation mask is in its compressed Condition in the housing, it can be easily transported. For this purpose, a pendant or keychain (Fig. 1) can be provided, which is attached to the housing.
Fig. 2 zeigt die erfindungsgemäße Beatmungsmaske 2 in ihrem Gebrauchszustand. An der Oberseite der Maske ist eine nor¬ mierte Öffnung 4 vorgesehen, durch die Atemgas eingeblasen werden kann. Unter dieser Öffnung 4 befindet sich ein Rück¬ schlagventil 5.2 shows the respiratory mask 2 according to the invention in its state of use. A normalized opening 4 is provided at the top of the mask, through which breathing gas can be blown in. A check valve 5 is located below this opening 4.
Die Form des eingeschweißten Schaumstoffkörpers (Fig. 1) entspricht im Gebrauchszustand (Fig. 2) einem etwa dreiecki¬ gen, rund umlaufenden Wulst zum Abdichten auf dem Gesicht (domartige Glocke) . So kann die Maske abdichtend und Mund und Nase umschließend auf das Gesicht gepreßt werden, ohne daß Nase oder Mund eingeengt werden, über einen angeschlos¬ senen Beutel oder über einen Beatmungsschlauch oder mit Hilfe des Mundes kann Luft in die Maske und somit in den Mund und die Nase des Patienten geblasen werden. The shape of the welded-in foam body (FIG. 1) corresponds to an approximately triangular, all-round bead for sealing on the face (dome-like bell) when in use (FIG. 2). For example, the mask can be sealed and the mouth and nose can be pressed onto the face without the nose or mouth being constricted, air can be introduced into the mask and thus into the mouth and mouth using a connected bag or a ventilation tube or with the help of the mouth to blow the patient's nose.
